Write an instruction sequence to swap the upper four bits and the lower four bits of accumulator A (swap bit 7 with bit 3, bit 6 with bit 2, and so on). Write a program to count the number of elements in an array whose bits 3, 4, and 7 are 0s. The array has N 8-bit elements and is stored in memory locations starting from exist1000.
